Just think about it
right angles are the very definition of perpendicular
how many right angles in a full rotation? 4
answer is 4
Let the number be 'x'.
Three times a number will then give 3x
Therefore the equation will be:
Answer:
B
Step-by-step explanation:
The gcf is 4 therefore all you have to do is look at the number not in ()
Please, use " ^ " to denote exponentiation: p(t) = t^2 + 5t + 6.
To find the critical points, differentiate p(t) with respect to t, set the result = to 0, and then solve the resulting equation for t:
p '(t) = 2t + 5 = 0
Solving for t: 2t = -5, and so t = -5/2. (-5/2, p(-5/2)) is the critical point. That evaluates to (-5/2, -0.25). This happens to be the vertex of a parabola that opens up.
Any number from 21-98 is between 20 and 99.
